RADIATOR.

Application filed June 10, 1920.

To all whom it may concern:

Be it known that I, EMIL OCHSNER, a citizen of the United States, residing at Sutton, in the county of Clay, State of Nebraska, have invented certain new and useful Improvements in Radiators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to radiators for motor vehicles, and more especially to those having vertical water tubes; and the objects of the same are twofold.

First, it is intended to produce a radiator having its tubes arranged in banks and the banks so spaced from each other that all parts of any tube may be reached by a proper tool, as for instance a soldering iron whereby a leak in any tube may be repaired.

Second, it is intended to produce a radiator whose tubes are arranged in banks, the disposition of the tubes and of the banks being such that there is no clear line through the radiator from front to rear, and therefore, air currents flowing through this radiator as the automobile progresses are deflected and caused to exert increased cooling effect on the tubes.

Details of one embodiment carrying out these ideas are set forth below and shown in the drawings, wherein:

Figure 1 is a perspective view of this radiator complete.

Figure 2 is a horizontal section.

Figure 3 is a diagrammatic plan View of one of the plates, showing the disposition of the tubes therethrough.

Structurally the radiator comprises a casing 1 having appropriate brackets 2 by which it may be mounted on the frame work of the automobile, and a filli g nipple 3 at the top; and within this casing is mounted a hollow frame work comprising upper and lower headers 4 and 5 connected by upright side passages 6 and 7, and across the space within this frame work are preferably mounted transverse plates or fins 8. Vertical water tubes 9 open at their ends into the headers and their bodies pass through holes in said plates.

Referring now to the diagram of Figure 3, it will be noted that the tubes are disposed in rows or banks extending obliquely across the plate 8, each bank illus- Specification of Letters Patent.

trated herein as made up of six tubes. Taking the bank designated 10 as an illustration, the left side of its second tube stands in a plane 11 which, if extended to the rear, would cut its third tube, and the right side of the third tube, if extended forward in a plane 12, would cut the second tube. This arrangement is maintained throughout all the tubes in every bank, and it may be described by stating that the tubes partly overlap each other. In the present instance, each bank is made up of a group of tubes which stand in a straight row, and the tubes in the bank are nearer to each other than are the nearest tubes in two contiguous banks; or in other words, the banks are further apart than are the tubes in the banks themselves. Furthermore, it will be noticed that the front tubes of all the banks stand in one row which forms a straight line across the radiator from side to side, and the same is true with the tubes in the next row, and so on. Finally, it will be noticed that one or more of the tubes in the rearmost rows of one bank as indicated at 13, stands farther to the left as shown by the arrow 1 1 than one or more of the tubes 15 in the foremost rows of the next contiguous bank. Or, to put it in other words, the tubes of the several banks overlap each other.

The result is that at no point throughout the space exposed within the frame work of this improved radiator, can a straight line be drawn through it from front to rear, and therefore, when the radiator is driven forward as the car progresses, all cur rents of air blowing through it must strike and be deflected by the tubes-hence their cooling effect is increased. As shown also in Figure 3, an ordinary soldering iron 16 can be introduced to reach most all points around the tubes in the foremost and rearmost rows, and all other tubes can be reached by a special soldering iron 17 or 18, particularly one having its tip bent or deflected as shown at 19. This possibility flows from the fact that, although the tubes in any bank are quite close together, the banks are so spaced from each other as to permit introduction of the'tools.

It is not important to this invention how the ends of the tubes are connected with the headers although, of course, the connection must be water tight. Nor are we concerned with the inlet of water from the engine to the radiator and its return to the engine after cooling. Again, the number, construction, and disposition of the plates or fins, maybe left to the manufacturer. It is even possible that the tubes could be horizontal, but I prefer them vertical as shown. Currents of air flowing through this radiator, possibly accelerated by the action of a fan behind it, must necessarily be deflected by striking certain of the tubes because of the specific disposition of the latter, and the water within these tubes will be cooled thereby and will descend, while the warmer water will rise in the side passages 6 and 7- thus maintaining a constant circulation.

Obviously the precise detailsof construction and the number of plates and tubes are not important; also, instead of round tubes I may use those which are oval in cross section or of other shape, and possibly tubes which are crimped or corrugated so as to permit them to expand without bursting.

The constant rapid circulation of water through this radiator results in its more rapid cooling and therefore prevents overa radiator cover or other protector.

What is claimed is: A radiator for automoblles'havnig headers and water tubes connecting the same, they tubes being disposed in banks or series arranged in or in like relation to the path of movement of the radiator, with adjacent tubes in each bank overlapping each other transversely with relation to planes parallel with the path of movement and with the front and rear ends of adjacent banks or series overlapping each other transversely with relation to planes parallel with the path of movement, thebanks being spaced transversely to give access for repair to all of the tubes in each series.

In testimony whereof, I affix my signature, in the presence of two witnesses.
